Abstract

In this study was aimed to describe the relationships between morphometric characters and total length of Nemipterus randalli. A total of 107 samples were collected from Iskenderun Bay in November 2018. The results show that estimates of total length of this species through of morphometric character are reliable. Linear regressions showed the best accuracy for all relationships between morphometric characters and total length. Among obtained relationships, the best fit was recorded between total length and head length, while the lowest value of coefficient of determination was also determined between total length and horizontal mouth gape. Establishing morphometric relationships can provide an alternative to back‐calculation of fish length and can provide information that aids in understanding complex relationships between predator and prey size. The equations generated to obtain the total length of the fish using morphometric character data can be used in dietary studies of top predators and in paleontological studies.

İskenderun Körfezi’ndeki Nemipterus randalli (Russell, 1986)’nin Morfometrik İlişkileri

Abstract

Bu çalışmada, Nemipterus randalli'nin morfometrik karakterler ile toplam uzunluğu arasındaki ilişkileri tanımlamak amaçlanmıştır. Kasım 2018 tarihinde toplam 107 örnek İskenderun Körfezi'nden elde edilmiştir. Sonuçlar, morfometrik karakter üzerinden bu türün toplam uzunluğunun tahminlerinin güvenilir olduğunu göstermektedir. Doğrusal regresyonlar, morfometrik karakterler ve toplam uzunluk arasındaki tüm ilişkiler için en iyi doğruluğu gösterdi. Elde edilen ilişkiler arasında en iyi uyum toplam uzunluk ve baş uzunluğu arasında kaydedilmiş iken, en düşük belirleme katsayısı değeri ise toplam uzunluk ile yatay ağız açıklığı arasında belirlenmiştir. Morfometrik ilişkilerin kurulması, balık uzunluğunun geriye doğru hesaplanmasına bir alternatif sağlayabilir ve avcı ile av boyutu arasındaki karmaşık ilişkilerin anlaşılmasına yardımcı olan bilgiler sağlayabilir. Morfometrik karakter verilerini kullanarak balıkların toplam uzunluğunu elde etmek için oluşturulan denklemler, en iyi avcıların beslenme çalışmalarında ve paleontolojik çalışmalarda kullanılabilir.
